BACKGROUND OF THE INVENTION

[0002] Serotonin is a neuromodulator capable of inducing and modulating a wide variety of behavioral functions such as sleep, appetite, locomotion, sexual activity and vascular contraction. It is accepted that serotonin activity is mediated by its interaction with receptors, designated serotoninergic receptors of 5-HT (for 5-hydroxytryptamine) receptors. Molecular biology studies as well as pharmacological studies have revealed the existence of a large number of subtypes of 5-HT receptors. The 5-HT receptors which have been described to date belong either to the family of receptors associated with ion channels (5-HT3 receptors), or to the family of receptors which interact with G proteins and which possess seven transmembrane domains. Moreover, analysis of the amino acid sequences has shown that the 5-HT receptors which interact with G proteins may be subdivided into six distinct groups: 5-HT1 receptors, comprising the mammalian subtypes 5-HT1a, 5-HT1b, 5-HT1d, 5-HT1e and 5-HT1f, as well as three Drosophila 5-HT receptors; 5-HT2 receptors comprising three subtypes, 5-HT2a, 5-HT2b and 5-HT2c; 5-HT4 receptor; 5-HT5 receptor; 5-HT6 receptor; and 5-HT7 receptor.

[0003] Drugs with affinity for 5-HT2 receptors are used to treat schizophrenia, Parkinsonism, and anxiety disorders. The 5-HT2c receptor subtype has been particularly interesting to investigators searching for the molecular bases of neuropsychiatric disorders. The 5-HT2c receptor is widely expressed in the brain where it is involved in regulating endocrine responses. Particular responses include the production and secretion of adrenocorticotropic hormone, oxytocin and prolactin. Genes for mouse, rat and human (Saltzman et al., Biochem. Biophys. Res. Commun. 181:1469, 1991) 5-HT2c receptors have been cloned. Burns et al., Nature vol. 387 15 May 1997 pp. 303-308 describes rat 5-HT2c receptor isoforms resulting from RNA editing events involving transcripts encodong the serotonin receptor. The functional state of 5-HT2c receptors in normal controls and various patient groups has been studied in vivo by administering 1-(3-chlorophenyl)piperazine (mCPP), a non-selective 5-HT2c agonist, and measuring hormonal and psychological responses. In alcoholism, panic disorder, seasonal affective disorder and obsessive-compulsive disorder, mCPP has been shown to induce different hormonal and psychological responses in patients and controls.

SUMMARY OF THE INVENTION

[0005] The invention includes mouse serotonin 5-HT2c receptor isoforms having amino acid replacements at one or more positions of the previously known mouse serotonin 5-HT2c receptor polypeptide sequence, specifically at one or more of positions 157, 159 and 161. The invention also includes isolated or purified isoforms, DNA encoding the isoforms, antibodies with specific binding to the receptor isoforms, assays for detecting the receptor isoforms, and expression vectors encoding the receptor isoforms.

DETAILED DESCRIPTION OF THE INVENTION

[0006] The invention includes an isolated polypeptide comprising a sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e) wherein the polypeptide has serotonin activity. These polypeptides are mouse serotonin 5-HT2c receptor isoforms having amino acid replacements at one or more positions of the previously known mouse serotonin 5-HT2c receptor polypeptide sequence, specifically at one or more of positions 157, 159 and 161.

[0007] The polypeptides are useful for identifying ligands which bind with the serotonin 5-HT2c receptor and modulators of the serotonin 5-HT2c, and for identifying drugs with affinity for 5-HT2 receptors which are used to treat schizophrenia, Parkinsonism, and anxiety disorders.

[0008] The invention also includes a method for identifying modulators of a polypeptide comprising a sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e), comprising contacting in the presence of 5-HTa molecule or a mixture containing different molecules with a recombinant cell expressing at its surface a polypeptide of claim 1, under conditions permitting interaction between the polypeptide and 5-HT, and detecting molecules capable of modulating the activity of the polypeptide in the presence or absence of 5HT.

[0009] The invention also includes isolated nucleotide sequences coding for a polypeptide comprising a sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e), or the complementary strand, including such nucleotide sequences consisting of genomic sequences, cDNA sequences, RNA sequences, synthetic sequences and semi-synthetic sequences. Also within the the invention are such sequences placed under the control of signals permitting expression of the polypeptide in a host cell.

[0010] The invention also includes recombinant cells comprising nucleotide sequences of the invention, including eukaryotic and prokaryotic cells, and vectors for transforming the cells.

[0011] The invention also includes mammalian cell membranes comprising a polypeptide sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e) wherein the polypeptide has serotonin receptor activity. Optionally, the mammalian cell membranes are free of other receptor proteins. The mammalian cell membranes may be prepared from mammalian cells containing cDNA which encodes any of the polypeptides. The mammalian cells are transfected with recombinant DNA comprising vector DNA and cDNA which encode the polypeptides.

[0012] The invention also includes a method for identifying ligands of a polypeptide comprising a sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e), comprising contacting a molecule or a mixture containing different molecules with a recombinant cell expressing at its surface one of the polypeptides, under conditions permitting interaction between the polypeptide and the molecule, and detecting molecules bound to the polypeptide.

[0013] The invention also includes a method for identifying modulators of a polypeptide comprising a sequence selected from the group consisting of (a) SEQ ID No. 3, (b) SEQ ID No. 5, (c) SEQ ID No. 7, (d) SEQ ID No. 9, (e) SEQ ID No. 11, and (f) fragments of (a), (b), (c), (d), and (e), comprising contacting in the presence of 5-HTa molecule or a mixture containing different molecules with a recombinant cell expressing at its surface a polypeptide of claim 1, under conditions permitting interaction between the polypeptide and 5-HT, and detecting molecules capable of modulating the activity of the polypeptide in the presence or absence of 5HT.

[0014] The present invention further includes antibodies specific for the serotonin receptor isoform proteins of the invention which do not bind to the receptor as described by Yu et al. in GenBank X72230.

[0015] The term “isolated” refers to material that is removed from its original environment (e.g., the natural environment if it is naturally occurring). For example, a naturally-occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or DNA or polypeptide, separated from some or all of the coexisting materials in the natural system, is isolated. Such polynucleotide could be part of a vector and/or such polynucleotide or polypeptide could be part of a composition, and still be isolated in that such vector or composition is not part of its natural environment.

[0016] The mouse serotonin 5-HT2c subtype cDNA isoforms were subcloned into the expression vector pE3 which is modified as described below from pCEP4 (Invitrogen, Carlsbad, Calif.). Transient expression in HEK293e cells (Invitrogen, Carlsbad, Calif.) was accomplished by transfection of the cloned receptor cDNAs under the control of a CMV promoter into mammalian cells (e.g., HEK293e cells). Membranes prepared from the transfected cells are utilized for the determination of binding affinity, selectivity and specificity of the receptors for various ligands. Stable expression of the receptors in mammalian cells (e.g., CHO, HEK 293) is achieved after integration of the transfected cDNA into the chromosomes of the host cells. These stable cell lines constituently express the cloned receptors and can be propagated infinitely. Stable cell lines expressing the receptor cDNAs individually can be used in the binding assay to measure the affinity and selectivity of the receptors for serotonin agonists, antagonists and enhancers. These cells can also be used in functional assay to determine the agonist activity of any ligand.

[0017] Membranes prepared from transfected (HEK 293e) cells were utilized in a binding assay to measure the affinity of the receptors for radiolabeled agonists, e.g. [3H]5HT or [3H]mesulergine. The binding assay was performed by incubating membranes with increasing concentrations of radiolabeled agonists. Bound ligand was separated from free ligand by filtration. Bound radioactivity was measured by scintillation counting. Substances which bind to or enhance binding to expressed receptors in cells can be identified in competition binding assays with radiolabeled agonists. For the competition binding assay, membranes were incubated with a fixed concentration of radioligand and various concentrations of unlabeled agonists or antagonists.

[0018] Functional assay was performed by loading the receptor-expressing with [3H]inositol, incubating the cells with a ligand and measuring the accumulation of [3H]inositol trisphsophate inside the cells.

[0019] A transient expression system can be established by microinjection of in vitro transcribed mRNA from the cloned receptor cDNAs into Xenopus oocytes. The expression system allows measurement of the biological effects upon activation of the expressed receptors with ligand binding.

[0020] In the procedure for generating the isoforms of the present invention, transcripts encoding the mouse serotonin 5-HT2c receptor subtype undergo RNA editing events in which genomically encoded adenosine residues are converted to inosines by the action of double-stranded RNA adenosine deaminases (see Burns et al., Nature vol. 387 May 15, 1997 pp. 303-308, which describes rat 5-HT2c receptor isoforms resulting from RNA editing events involving transcripts encodong the serotonin receptor). Sequence analysis of complementary DNA isolates from dissected mouse brain regions have indicated the tissue-specific expression of new receptor isoforms encoded by distinct RNA species. Editing of 5-HT2c receptor messenger RNAs alters the amino acid coding potential of the predicted second intracellular loop of the receptor and can lead to altered efficacy of the interaction between receptors and their G proteins. As shown in Table 3, the 5HT EC₅₀ value is dependent on the amino acid sequence at position 157/159/161.

[0021] The table below compares a partial amino acid sequence of the published mouse serotonin 5-HT2c receptor (SEQ. ID No. 1) and the corresponding partial nucleotide sequence of the published mouse serotonin 5-HT2c receptor RNA, with amino acid sequences and nucleotide sequences corresponding to new isoforms of the mouse serotonin 5-HT2c receptor in the location of sequence variation. The isoforms have amino acid sequences identical to the published mouse serotonin 5-HT2c receptor polypeptide sequence except for specified amino acid replacements at one or more positions of the published mouse serotonin 5-HT2c receptor polypeptide sequence, specifically at one or more of positions 157, 159, and 161: TABLE 1 Amino acid position SEQ.

EXAMPLE

[0024] Mouse brain cDNA (Clontech Catalog#7130-1) was used as a template to amplify the mouse 5HT2c receptor cDNA. The PCR oligos used in this amplification were a sense oligo 5′-CTGAAGCAATAAATGGTGAACCTGGGCACTG which hybridizes to the start codon and several residues following the start codon and an anti-sense oligo 5′-GCGTCTAGATTTCCTGTAGGAAAGCTGCGCTG which hybridizes to the 3′-untranslated region following the stop codon. The PCR product thus contains a mixture of the most abundant isoforms of mouse 5HT2c receptor cDNA. To determine the sequence of mouse 5HT2c receptor cDNA, the PCR product was cut with XbaI restriction enzyme, and ligated to the vector pE3 which was treated with the restriction enzyme Stu I and XbaI.

[0025] The vector pE3 was modified from the pCEP4 vector (Cat# V044-50, Invitrogen, Carlsbad, Calif.) as described below. (1) To remove the eukaryotic expression cassete downstream of oriP segment (origin of replication from Epstein Bar virus), pCEP4 was digested with restriction enzyme Xba I and Sal I, then blunt ended with the Klenow fragment of DNA polymerase and self-ligated with T4 DNA ligase. (2) To replace the EBNA-1 (Epstein-Barr virus nuclear antigen) upstream of the oriP segment with a eukaryotic expression cassete, the resulting plasmid from step 1 was digested with restriction enzyme Xmn I and Sph I, and ligated with the XmnI-XhoI DNA fragment from pcDNA3.1 kyg(+) (Invitrogen, cat # V870-20) containing CMV (cytomegalus virus) immediate early gene enhancer-promoter region and the Xho I-BamH I fragment from pCDM8 (Invitrogen Cat # V308-20) containing the SV40 intron/poly A signal and a BamH I-Sph I linker. (3) The multiple cloning site was modified with synthetic overlapping oligos containing unique sites of Sac I, Age I, Stu I , KpnI, Xho I, Sse8387 I, Not I and Xba I. Taken together, in the final plasmid pE3, EBNA-1 is deleted, the expression cassete is moved to the upstream of oriP and transcription is in the same direction of replication.

[0026] After the mouse 5HT2c receptor PCR product has been ligated with the pE3 vector, the ligation mixture was transformed into the E. coli host DH5α. Single colonies were picked from the transformation plate, followed by plasmid DNA preparation from each clone. The sequence of the mouse 5HT2c receptor cDNA was determined by standard fluorescence-based dideoxy DNA sequencing (Perkin-Elmer, Foster City, Calif.).

[0027] The plasmid carrying mouse 5-HT2c cDNA (abbreviated as m2C-pE3) was transfected into 293-EBNA cells (Invitrogen, Cat # R620-07) by the method of lipofection. Briefly, 2 μg plasmid DNA was diluted in 400 μl Dulbecco's phophate-buffered saline and mixed with 30 μl lipofectamine reagent (GIBCO-BRL, cat # 10964-913). After 20 min incubation, the mixture was diluted with 5 ml OPTI-MEM I reduced serum medium (GIBCO-BRL, cat #31985-013) and transferred to a T75 flask of 293-EBNA cells which were grown overnight. After 5-7 hr incubation at 37° C., the transfection medium was aspirated off. The cells were washed twice with growth medium and cultured for 48 hr in CO₂ incubator. The cells were then split and cultured in the medium containing 250 μg/ml hygromycin. The untransfected cells were killed, and the surviving cells collected for continuing culture or assaying.

[0028] A number of other cell lines are suitable for expressing mouse 5-HT2c receptors, such as CHO, HEK293, COS, or Hela cells. Transfection can also be carried out by other methods, e.g. electroporation, calcium phophate precipitation, or DEAE-Dextran.

[0029] The recombinant 293-EBNA cells expressing mouse 5-HT2c receptors were used in receptor binding and functional assays. To prepare membranes for binding assays, the cells were homogenized in hypotonic buffer (50 mM Tris-HCl, pH7.4, 5 mM MgCl₂). After removal of nuclei by low speed centrifugation at 1000 g, the membranes were pelleted by centrifugation at 45,000 g for 30 min.

[0030] Ligand Binding Assays

[0031] Ligand binding assays are commonly used to determine how well a compound binds to a receptor. [3H]mesulergine or [3H] 5-HT binding assays were carried out with the mouse 5HT2c membrane preparations. Radioligand was incubated with the membranes in binding buffer (50 mM Tris-HCl, pH7.4, 5 mM MgCl, 0.1% ascorbic acid and 10 uM pargylin) in the presense or absense of unlabeled compounds. After 30 min incubation at room temperature, the binding reaction was terminated by filtering the mixture through GF/C filters. After washing off the unbound ligand, the amount of radioligand-receptor complex trapped on the filter was measured by scintilation counting. The binding affinities (Kd, IC₅₀ or Ki) of the compounds for mouse 5-HT2c receptor could be calculated from the binding assays.

[0032] Functional Activity Assays

[0033] Second messenger assays are used to determine the functional activity of a compound upon binding to a receptor. It is well established that 5-HT2c receptor is coupled via G-protein of Gq/11 class to phosphatidyl-inositol (PI) hydrolysis resulting in the production of two second messengers, inositol trisphosphate (IP3) and diacylglycerol (DAG). The functional activity of mouse 5-HT2c receptor was determined by measurement of the increases in the intracellular inositol phosphate level following agonist stimulation (PI assay). Transfected 293EBNA cells were seeded into multiwell plates and cultured in medium containing [3H]-myo-inositol (2 uCi/ml) for 24-72 hr. After labelling period, cells were washed, and preincubated for 30 min in balanced salt buffer containing 10 mM LiCl. Cells were then stimulated in the same buffer with agonist 5-HT or test compounds for 45 min at 37° C. After removal of the medium, the reaction was stoped by addition of 10 mM formic acid. Cell extracts were collected after 30 min incubation at 4° C., the inositol phosphate fraction was then isolated by anion exchange chromatography and quantitated by scintillation counting. The potency (EC50) and efficacy (% maximal response) of a compound activating mouse 5-HT2c can be determined.
